Bioinspired Shape‐Memory Hook Fasteners With Programmable Interlocking and Silent Release
Advanced Engineering Materials, EarlyView.Bioinspired hook fasteners made from epoxy shape‐memory polymers are shown to switch between strong, secure attachment and gentle, silent release when heated. By combining programmable geometry and material response, these adaptive fasteners outperform commercial systems in strength and noise control, enabling new solutions for robotics, medical ...

Asymmetric synthesis of (−)-codonopsinine
Tetrahedron Letters, 2011 Abstract The asymmetric synthesis of (−)-codonopsinine was achieved in 7 steps (from commercially available tert-butyl crotonate) in 5% overall yield and >99:1 dr. The key step in this synthesis involved ring-closing iodoamination of a functionalised homoallylic amine, which occurred with concomitant N-debenzylation, to give a 3-iodopyrrolidine that ...
